 Abstract

Video surveillance in dynamic scenes is a great and useful system to meet the current and future challenges of security across the word. Because many forms of inhuman activity, such as terrorism and theft, etc., are beginning to pose a threat to the global community, security in public spaces has become more and more important in recent years. Tracking people in crowded environments is one of the most challenging tasks in a public security system because continuous human object tracking is very essential for public security to reduce human criminal activities. A very basic and critical task in any human object tracking system is the detection of moving objects in captured video sequences. Background subtraction method (BSM) is one of the most popular approaches to detect foreground objects. The key issue is that during foreground segmentation, the shadow merges with moving objects and could be mistaken for a foreground object. The recognition and elimination of shadows is an important pre-processing step to improve the performance of human object tracking systems, because the presence of shadows affects the reliability of human object tracking system. The existing gradient-based shadow removal approaches are discussed in this paper in order to improve the multiple human object tracking system's accuracy.

 Abstract

In modern technology, face recognition system has received great attention. Several desktop, web and mobile applications make use of face recognition for security purpose. A major point of concern is the ability of the face recognition system to prevent an authorised person from having access to the application. Face spoofing through pictures and videos often threatens the system module of a face recognition system by disguising as a real image. A detection technique for face spoofing attack must be such which could be relied on against different mode of attacks. A novel approach to detect spoofed images needs to be developed to reduce and eradicate the effects of spoofing. Several researchers have proposed detection techniques. Some of these past attempts have been reviewed in this paper. I propose in this study, an ensemble machine learning approach for detecting face spoofing. Random forest algorithm an ensemble learning and neural network were used for face spoofing detection. Neural network gave a better classification result.

 Abstract

Introduction: cancer is a part of our life but it's not our whole life. Today we are facing a lot of serious kind of diseases in all over world at all aspects. Cervical cancer is also a serious disease arising from the cervix. It is due to the growth of abnormal cells that have ability to invade or spread to other parts of the body. Cervical cancer is largely preventable disease but worldwide it is one of the leading causes of cancer death in women. The primary cause of cervical pre-cancer and cancer is persistent or chronic infection with one or more of the high-risk types of human papillomavirus (HPV). HPV is the most common infection acquired during sexual relations, usually in early sexual life. Cervical cancer deaths can be prevented through four key interventions: vaccination, screening, timely follow up after abnormal test results, and early treatment. Objectives:To assess the level of knowledge regarding cervical cancer among G.N.M 1st year students. To determine the association between the knowledge and their selected some demographic variables. Method: Google Scholar, pub med, searched for narrative reviews, to evaluate the knowledge regarding prevention of cervical cancer among the G.N.M 1st year students. Result: 42% of first participants had average knowledge, 33% of participants had poor knowledge and 25% of participants had good knowledge. According to above results 50 % are effective. Conclusion: through different studies we found that G.N.M 1st year students had average knowledge regarding the prevention of cervical cancer. It is very necessary to provide adequate knowledge regarding cervical cancer. Keywords: knowledge, prevention, treatment, G.N.M, vaccination, screening, follow-up, test results.

 Abstract

Systemic lupus erythematosus (SLE) is a systemic disease of unknown etiology with variable course and prognosis. Lupus nephritis (LN) is an important disease manifestation of SLE that has a significant impact on patient outcomes. Immunosuppression therapy has allowed the disease to be controlled while improving life expectancy and quality of life. Various studies conducted around the world over the last few decades have clarified the role, dose, and duration of immunosuppressive agents currently in use, as well as provided evidence for new agents such as mycophenolate mofetil, calcineurin inhibitors, and rituximab. However, there is still a need to develop new and more targeted therapies with fewer side effects. In this review, the current evidence of the treatment of LN and its evolution, and new classification criteria for SLE has been discussed. In addition, the rationale for low-dose intravenous cyclophosphamide as an induction agent, followed by azathioprine as a maintenance agent, with an emphasis on an individualized and holistic approach, has been provided.

The bioefficiency of plants and their derivatives has recently received renewed attention. The purpose of this study was to compare the Phytochemicals, antioxidant and antimicrobial activity Of curcuma caesia and micropropagated curcuma caesia. A variety of phytoconstituents, including flavonoids, terpenoids, alkaloids, proteins, carbohydrates, tannins, and glycosides, were found in the plant extracts taken from the rhizome by means of qualitative chemical analysis. Plant derived secondary metabolites make up a significant segment of natural product based pharmaceuticals especially from the herbal medicinal plants. Secondary metabolites screening done by using HPTLC at wavelength 366nm, different separation band on TLC plate were found. The antioxidant activity is performed with reducing power assay Which have reduction potential react with the potassium ferricyanide to form potassium ferrocyanide, which then react with ferric chloride to form ferric-ferrous complex that give absorbance at 700nm. Higher the concentration of the plant extract higher the antioxidant. Curcuma caesia have phenolic compounds which an act as antimicrobial agents. in present study it can measured by the disc diffusion method against the gram-positive bacteria, gram-negative bacteria and Candida albicans fungal.

 Abstract

The proliferation of image captioning applications has greatly improved the accessibility and functionality of visual content for people with diverse needs. However, these applications often lack essential features such as text-to-speech and people counting capabilities, which are necessary for creating a more inclusive and accessible user experience. This research paper explores the integration of text-to-speech and people counting features into image captioning applications. We present a novel approach for incorporating these functionalities and evaluate the performance of the resulting system using standard metrics. Our results demonstrate that the proposed approach significantly improves the accessibility and usability of image captioning applications for a broad range of users. The research presented in this paper provides valuable insights into the potential benefits of combining image captioning with text-to-speech and people counting technologies, and highlights the need for continued research in this area to further enhance the accessibility and functionality of image captioning applications.

 Abstract

The economy and the environment around the world are changing very rapidly. Practices for managing human resources are likewise evolving and expanding in scope. Employees are much more worried about how they will prosper financially in this time of economic transformation and are striving to excel professionally. This has led to the addition of secondary job with additional remuneration with a different company on top of their primary job. This practice is called as employee moonlighting. In the teaching profession, holding multiple jobs is more frequent. This research paper is descriptive in nature and studies the concept, types, causes and consequences of moonlighting practices with the help of existing literature and attempts to give new insight regarding moonlighting practices among teachers.
